Brassiere mold-forming machine

Abstract

Abstract In preferred embodiments of the invention, there is provided a brassiere forming machine for molding brassiere garments from fabrics of textile or plastic sheet material placed transversely across the mold plate of a female bottom mold selectively heated to a predetermined temperature and compacted between that female mold and a pneumatically downwardly pressed male mole separately selectively heated to the same or another predetermined temperature, with the respective molds being a part of a small circumscribing fabric-mounting lower and upper plates respectively in aligned opposing relationship each circumscribing plate defining a minimum annular or recessed space in which the respective mold is mounted in order to reduce to a minimum waste fabric to be trimmed from around the molded brassiere once the molding phase is completed, and each mold plate on which the mold and circumscribing plate are mounted being secured by a simple clamping device or easily removed bolt and/or nut at each four corners, for example, for facilitating simple and speedy removal and replacement of the respective mold plate and for intended replacement of a faulty mold and/or substitution therefor of an alternate sized mold in and during a normal course of operation, the respective circumscribing plates being mounted in a spring biased state toward one-another with lower-plate fabric mounting pins extending uprightly through apertures in an upper face of and spaced along the lower circumscribing spring-biased plate, and the upper circumscribing plate being spring-biased positioned in a downwardly directed state at a location below and movable concurrently downwardly with the upper male mold''s lower-most point during downward advancement pneumatically thereof during the fabric mold-compression such that the opposing circumscribing plates come into face-to-face engaging contact with one-another before the upper molds lower-most surface contacts the fabric previously laid across the upper faces of the lower mold and lower circumscribing plate and upright pins, the switch circuitry also being such that activation of the pneumatic compression and compacting of the fabric sheet is accomplished solely by simultaneous activation with separate human hands two separate distantly-spaced-apart activation buttons which must be both held in the activation state until such time as the molds become contacted against each other after which the circuitry provides for continued compaction after release of either or both buttons for a predetermined period of time as preset on a timer within the circuitry ranging from zero time to several minutes or the like as might be desired, there being a separate and separately regulatable thermostat for each of the molds and a separate preheat activation switch separate from the pneumatically compacting activation circuit(s), and also there being a light or buzzer signal automatically activated upon the molds reaching the advanced state of compaction thereby informing the operator that the required simultaneous activation of the buttons may be terminated manually by withdrawal of either or both hands from the activation buttons, and also there being provided circuitry for regulation of speed manually for the rate of advancement of the female mold downwardly such that the speed of operation of the machine may be adapted to the individual operator.
